Step 6: Neaten the pipes
U-shaped curve
wall
drain hose
1. The pipes should be placed along the wall,
bent reasonably and hidden possibly. Min.
semidiameter of bending the pipe is 10cm.
2. If the outdoor unit is higher than the wall
hole, you must set a U-shaped curve in the
pipe before pipe goes into the room, in order
to prevent rain from getting into the room.
Installation of outdoor unit
Use vacuum pump
1. Remove the valve caps on the liquid
valve and gas valve and the nut of
refrigerant charging vent.
2. Connect the charging hose of piezometer
to the refrigerant charging vent of gas
valve and then connect the other
charging hose to the vacuum pump.
3. Open the piezometer completely and
operate for 10-15min to check if the
pressure of piezometer remains in
-0.1MPa.
4. Close the vacuum pump and maintain
this status for 1-2min to check if the
pressure of piezometer remains in
-0.1MPa. If the pressure decreases,
there may be leakage.
1. With leakage detector:
Check if there is leakage with leakage detector.
2. With soap water:
If leakage detector is not available, please use soap water for leakage detection.
Apply soap water at the suspected position and keep the soap water for more than 3min.
If there are air bubbles coming out of this position, there's a leakage.

Step 8: Leakage detection
Step 7: Vacuum pumping
5. Remove the piezometer, open the valve core of liquid valve and gas valve completely
with inner hexagon spanner.
6. Tighten the screw caps of valve and refrigerant charging vent.
7. Reinstall the handle.
